Any ideas of how to loosen the sink drain?
Soak the edge of the drain basket where it meets the porcelain sink with Mineral Spirits .
Let it soak for 5 minutes . It will soften the silicone . Take a narrow plastic scraper and work around the edge . Remove what silicone you can peel off and soak the edge again.
If you plan on replacing the drain basket , you can use the plastic scraper to carefully pry up the edge of the basket while keeping the silicone wet with the Mineral Spirits . As you know , just be careful with the porcelain finish.
